Attacking a creature, making a shove attempt, spotting a hidden secret, and picking a lock are all examples of die rolls, which are the main method used to determine character success or failure in BG3. The amount of damage a character deals in combat is also determined by rolling a die. | |||
In most circumstances when a character makes a die roll their ability modifier and proficiency bonus will be added to the roll to determine the final result. The exception to this is the damage roll, which only adds a character's proficiency bonus if explicitly stated. | |||
Some rolls need to reach a certain value to be considered a success. This is usually done with a {{D20}}, and the target value is called the Difficulty Class of the roll. Rolling a 1 on a D20 is referred to as a Natural 1 | Some rolls need to reach a certain value to be considered a success. This is usually done with a {{D20}}, and the target value is called the Difficulty Class of the roll. Rolling a 1 on a D20 is referred to as a Natural 1 and rolling 20 is referred to as a Natural 20. On some rolls, these can have special effects, such as automatically failing or succeeding the roll, ignoring Modifiers and Difficulty Class. | ||

When a creature attacks another, it rolls a D20. The result is modified by its [[#Ability Score Modifier|Ability Score Modifier]] and [[#Proficiency Bonus|Proficiency Bonus]]. If the result matches or exceeds the [[Armor Class]] of the target, then the attack is successful. Otherwise, it's a failure; this could mean the attack was a miss, failed to hurt the target due to its armor, or the target was able to dodge or parry. | When a creature attacks another, it rolls a D20.

As a special case, a roll of 1 means that the attack fails regardless of bonuses and the target's Armor Class. This is called a Critical Miss. Likewise, a roll of 20 means the attack succeeds regardless of the target's Armor Class. This is called a Critical Hit. A critical hit also affects the result of the Damage Roll, though the details of how this will be implemented in the finished game are not known yet. Currently, a critical hit doubles all the damage dice involved in the damage roll, but not the modifiers. | As a special case, a roll of 1 means that the attack fails regardless of bonuses and the target's Armor Class.

For example, a successful hit with a [[Dagger]] will lead to a D4 being rolled to determine the damage (referred to as 1d4 damage), whereas a successful attack with a [[Greatsword]] will lead to two D6 being rolled (referred to as 2d6) for a total damage of 2 to 12. Being caught in a [[Fireball]] will cause 8d6 points of damage, though a successful Saving Throw (see below) can reduce it to half. | For example, a successful hit with a [[Dagger]] will lead to a D4 being rolled to determine the damage (referred to as 1d4 damage), whereas a successful attack with a [[Greatsword]] will lead to two D6 being rolled (referred to as 2d6) for a total damage of 2 to 12.

Advantage and Disadvantage can't stack. In other words, you never roll more than twice. Also, they cancel each other out, no matter how many sources of Advantage or Disadvantage you have. For instance, even if you have three sources of Advantage, and only one source of Disadvantage, they still cancel out each other completely, so you have neither. | Advantage and Disadvantage can't stack.

The lack of Proficiency in spell casting becomes apparent when you give a scroll such as [[Scroll of Guiding Bolt]] to a character that can't otherwise cast spells. Since [[Guiding Bolt]] uses an Attack Roll, but the character is not proficient in spell casting, they will have a lower chance to hit targets with the Guiding Bolt. | The lack of Proficiency in spell casting becomes apparent when you give a scroll such as [[Scroll of Guiding Bolt]] to a character that can't otherwise cast spells.
